Basic usage question

[John Aitchison]

Pardon my ignorance, I'm very new to browserify-ication; how do I use this (awesome looking) package? I'm not using Node, just a plain old vanilla apache webserver. The /example/index.html gives me an error "require is not defined", which makes sense, but I'm not sure how to proceed.

So far I've:

1.) browserify-ied index.js to a bundle.js
2.) included bundle.js in my index.html file (<script src=bundle.js></script>)

Have tried a number of things from this point on with no success. Thanks for any help and the great package

to use crypto browserify, all you need to do is browserify a node module that uses node's
crypto module. like many of the other core node modules, browserify will insert a javascript implementation to run in the browser.

if you have something like

//index.js
var crypto = require('crypto')
//etc

then do
browserify index.js > bundle.js
that is all. if that isn't working, you are probably missing something very basic.
you might want to try stackoverflow for questions like that?

Thanks, I almost posted on stackoverflow but this seemed a bit package specific, so I thought it would be better here. I'm not using node at all. I'd like to use crypto-browserify as in the "Browser" usage example here: https://www.npmjs.com/package/simple-random

E.g. in a plain vanillla index.html file, simple-random can be used as:

<script src="simple-random/dist/simple_random.js"></script>
<script>
var randomString = window.simpleRandom();
</script>

Sorry if you answered this, since I've only used node a few times for small local pet projects I'm not making the connection here.

This will work for any package or node module:

`"use strict";

/*
The node.js modules to be ported to the client must be added
to the window.myNodeObjects object.

Once bundle has been included in html page
    <script src="bundle.js"></script>
javascript calls can be made to myNodeObjects.* eg
    var hash = myNodeObjects.crypto.createHash('md5').update("plaintext").digest("hex");;

*/

// manually add required constants to crypto (not browserified)
var crypto = require('crypto');
crypto.constants = {
RSA_PKCS1_PADDING: 1
};

// update the browser's myNodeObjects object
window.myNodeObjects = {
crypto: crypto
};
`

if you browserify this package with the -s <name> flag then this package will be available under that name, you probably don't want to use crypto as the name as that's taken but you could do browserify -s bCrypto < index.js > bundle.js

[John Aitchison]

Ah, thank you guys. I was under the assumption that behavior was something that package authors had to specifically code to allow. None of the browserify tutorials I read have mentioned this, and for non-node apps this is essential. Thanks for the clarification, that helps immensely

see my fork to see some hassle free examples, i think the original repo example code is too old and has many unimplmeneted functions.

use bundle3.js on my repo

Apart from using the bundle3.js file provided by @ziyiwang, is there an "official" way to use crypto-browserify without using browserify? I don't have a Nodejs project or module at all, my only goal is to use Nodejs's crypto module in the browser because window.crypto lacks a lot of functions.
